Patent number: 4346229Abstract: Described is a process for producing unique reaction products from DMT process residue. In the process of this invention DMT process residue is reacted with an excess of dipropylene glycol to give normally liquid, aromatic polyester polyols which are compatible with Freon 11 blowing agent and with glycerol and hence have outstanding utility in the production of blown polyurethane and polyisocyanurate-polyurethane foams.Type: GrantFiled: May 1, 1980Date of Patent: August 24, 1982Assignee: Hercules IncorporatedInventors: Leighton K. Derr, Lyle B. Hawkins, Marlene J. Jones

Patent number: 4339595Abstract: Hexa(meta-,para-carboxyphenyl)benzene compounds. The esters are useful as plasticizers for polyvinylchloride, heat transfer agents, hydraulic fluids, and insulating oils. The acid is suitable as a cross-linking agent for polymers containing hydroxyl or amine groups.Type: GrantFiled: June 27, 1980Date of Patent: July 13, 1982Assignee: Standard Oil Company (Indiana)Inventors: Carl A. Udovich, Ellis K. Fields

Patent number: 4329490Abstract: Aqueous dispersions of oil-modified, carboxyl-containing, urethane polymers are prepared by reacting diisocyanates or their isocyanate-terminated prepolymers, with half-esters of hindered diols, especially 2,2,4-trimethyl-1,3-pentanediol, and anhydrides of polycarboxylic acids, preferably aromatic acids having at least three carboxylic groups, especially trimellitic anhydride. The urethane polymers are "oil-modified", i.e., extended with unsaturated fatty acid esterpolyols; and when neutralized with ammonia or amines can be dispersed in water to form especially desirable coating compositions. An organic phosphite may be incorporated in the compositions to control the development of hardness in films made from the aqueous dispersions and thereby avoid the formation of wrinkles in films that are made from the compositions.Type: GrantFiled: April 21, 1980Date of Patent: May 11, 1982Assignee: Textron, Inc.Inventors: Roy C. Williams, David R. Rogemoser

Patent number: 4328368Abstract: A method if provided for continuously hydrolyzing urethane foam in a vertically oriented hydrolysis reactor. In a preferred practice, a bed of foam particles is formed in the reactor. Superheated steam is flowed continuously upward through the bed at a temperature and rate such that only the foam particles then adjacent the bottom of the reactor are hydrolyzed and the bulk of the bed is not fluidized. Unreacted steam heats the unhydrolyzed foam. Liquid hydrolysis products are drained as they are formed to prevent hydrolysis-impeding liquid saturation of unhydrolyzed particles.Type: GrantFiled: May 5, 1980Date of Patent: May 4, 1982Assignee: General Motors CorporationInventors: Robert J. Salloum, Clifford C. Duff

Patent number: 4301044Abstract: Zwitterionic surfactant compounds are made readily biodegradable in the environment by the inclusion of a biochemically and/or hydrolytically labile chemical linkage located between the cationic and anionic charge centers of the compounds and anywhere from the second to the tenth atom distant from the cationic charge center. The biodegradable linkage is preferably an ester or amide. The alkoxylated zwitterionic surfactants herein exhibit outstanding particulate soil removal performance and are also effective in removing oily soils from fabrics, in addition to being readily biodegradable. Also described are detergent compositions containing the zwitterionic surfactants, and, optionally containing cosurfactants and detergent builders.Type: GrantFiled: January 22, 1980Date of Patent: November 17, 1981Assignee: The Procter & Gamble CompanyInventors: George E. Wentler, Joseph McGrady, Eugene P. Gosselink, William A. Cilley
